摘要：A total of 200 rainfall models were constructed with the slope ratio, rainfall intensity and rainfall duration as the variables for the stable state changes of the loess slope under rainfall conditions. Based on the Fredlund theory combined with the finite element numerical simulation software and the soil mechanics method, the changes of the volume water content and pore water pressure of the slope slope with the rain intensity and the rainfall time were analyzed, and the limit equilibrium theory was obtained. The results show that the rainfall time of the lower slope is different in different rainfall intensity. In the case of slope gradient, the corresponding stability coefficient will decrease with the increase of rain intensity. With the increase of rainfall, the contours of the volume water content and pore water pressure of the slope shoulder and slope foot are becoming more and more intensive.
